Aluminum ingots GOST 1131-76

 

Below is an overview of GOST 1131-76 "Alloys wrought aluminum ingots" with the release of its most important provisions. Article Numbering sections do not coincide with the section numbering standard. For professional use GOST 1131-76 please refer to the full and updated text of the standard.

Application area

GOST 1131-76 It applies to aluminum wrought alloys in pigs, которые предназначены для:

  • production of ingots, processed pressure,
  • podshihtovki melt in producing the aluminum alloy.

Aluminum ingots for ingot casting pressure processing

Chemical composition of the aluminum alloy in ingots, which are intended for pressure treatment, are presented in Table 1.

tabl1Table 1

Aluminum ingots for podshihtovki

Chemical composition of the aluminum alloy in ingots, which are designed to podshihtovki, are presented in Table 2.
tabl2Table 2

Aluminum scrap for the production of ingots

Aluminum scrap and waste in the production of ingots for podshihtovki shown in Table 3.
tabl3Table 3

The form, the size and weight of aluminum ingots

Ingots of the aluminum alloys can be of different shapes, размеров и массы:

  • длина: от 415 by 1750 mm;
  • ширина: от 93 by 1050 mm;
  • высота: от 60 by 450 mm;
  • масса: от 5 by 1600 kg.

Technical requirements for aluminum ingots

  • The surface of the aluminum ingot should have bays, neslitin, sags, slag and other foreign inclusions.
  • On the surface of large-sized ingots of aluminum cracks are not allowed deeper than 10 mm.
  • Admits the following stripping or cutting defects.
  • Pigs in the fracture must not contain slag and other
    foreign inclusions.
  • Aluminum alloys for pressure treatment can be made in the form of bars.

Marking of aluminum ingots

1 Each chushka should be marked, включающая марку (обозначение) алюминиевого сплава.
2 Для обозначения марки (обозначения) алюминиевого сплава на одном из торцов чушки наносят цветные полосы:

  • Aluminum alloy VD - one red, one green, одна черная;
  • алюминиевый сплав ВАК4 — одна красная и две черных;
  • алюминиевый сплав ВАК6 — одна красная и две синих;
  • алюминиевый сплав ВД1 — одна зеленая и одна белая;
  • алюминиевый сплав АВД1 — одна красная и одна желтая;
  • Aluminum Alloy AVD1-1 - one red, one yellow and figure 1;
  • алюминиевый сплав АКМ — одна синяя и три желтых;
  • алюминиевый сплав ВД95-1 — одна зеленая и две желтых;
  • алюминиевый сплав ВД95-2 — одна синяя и одна желтая;
  • алюминиевый сплав АКЦМ — одна синяя и две желтых;
  • Aluminium alloy 1105 - one green and two white.
